MACHINE FOR PERFORATING THE SIDES OF CAPSULES FOR BOTTLES.

SPECIFICATION forming part of Letters Patent No. 345.365, dated July 13.1886.

Application filed April 13, 11 86. Serial No. 198,779. (No model.)Patented in AnstriaIIungary May .26, 1886.

Bottles and Similar Receptacles, of which the following is aspecification.

This invention relates to further improvements upon the machine forperforating the sides of soft-metal capsules for the necks of bottlesand other like receptacles described in [5 the specification to myEnglish patent bearing date the 12th of June, A. D. 1882, No. 2,749,

and illustrated by Figs. 8 and 9 of the drawings thereunto attached; andit consists, essentially, in the combination, with a hollow 2Oflat-sided or polygonal-shaped mandrel receiving an intermittent rotarymotion, of a series of converging slides revolving with the mandrelandcorresponding in number with the flat sides on the mandrel, each slidecarrying at its inner end a group of punchesor perforators correspondingto holes or perforations in the respective sides of the mandrel, thepunches being so spaced round the fiatsided mandrel as to produceperforations equidis o taut from each other all round the capsule at oneoperation by the simultaneous action of all the groups of punches. Thesaid slides are forced inward and outward by a face -cam groove in astationary plate,along which travel 5 anti-friction rollers mounted onthe outer ends of the several slides. By my present improved arrangementthe operation of perforating is performed in a much more expeditions andefficient manner than by the appa- 0 ratus or means hitherto employedfor that purpose. I attain these objects by the mechanism illustrated inthe accompanying drawings, in

which Figure l is a front elevation of my improved 5 perforatingmachine,showing the several converging slides in their inward position-that isto say, with their punches or perforators entered into the perforatedsides of the central mandrel. Fig. 2 is a longitudinal vertical sectionof the same machine, taken along Fig. 3 is a detail the axis of themandrel.

side elevation of the pawl, 1ever,.and ratchetwheel for giving motion tothe said machine; and Fig. 4 is a fnllsized transverse section of themandrel and the inner ends of the punches, showing the equidistantspacing of the punches all round the mandrel. Fig. 5 is adiagram of anold arrangement of punches. Similar letters refer to similar parts throughout the several views.

A isthe fixed bracket or standard of the machine, bolted to anyconvenient work bench or table. I

B is a spindle turning in the bearings D D, to one end of which spindleis secured a hot low laterally-perforated mandrel. C, said spindle andmandrel being disposed centrally in the machine and having anintermittent rotary motion imparted thereto. This mandrel receives thecapsule to be perforated, and is flatsided or of polygonal form. say,for facility of description, having eight sides, as shown in thedrawings. Each flattened side is perforated to correspond with the sizeand spac' ing of the perforations to be produced round the sides of thecapsule. E is a solid block fixed on the spindle B. In combination withthe said central hollow fiat-sided perforated mandrel O, I employ asmany converging slides F F (each carrying a'group of punches) as thereare flattened perforated sides to the man drel, the several slidesworking in the out-er ends of arms G G, which are secured to the blockE, and which arms are provided with caps or cover-plates H, so as toconstitute guides for the said slides. In order to afford facility forthe ready removal and replacement of the hollow fiat-sided perforatedmandrel and the corresponding converging slides F F,I prefer to make themandrel proper, 0, separate 0 from the spindle B, and to screw orotherwise fix it into the guide-block E,as shown in Fig.2. This'mandrelis, by preference, made slightly tapering toward its outer or front end,and it is formed with an internal cavity or chamber, 5 a, for thereception i f the punchings or fragments which escape through theapertures 11 in the front end thereof as it rotates.

c c, Fig. 2, are the thin flat perforated sides of the mandrel. I

d is a perforated guide, fixed to the mandrel so as to surround the sameand to turn along therewith, in order to protect the ends of the punchesor perforators of each group of punches I I, attached to the inner endsof the slides F, and to guide them accurately into the correspondingholes in the sides of the mandrel. The slides Fare caused to travelround along with the guides G and mandrel O by an intermittent motion,so that the group of punches or perforators mounted on the inner 3 endof each slide shall always work in its own set of perforations in thecorresponding lateral face of the mandrel.

K K are anti-friction rollers working freely along the stationary-facecam-groove L, formed 5 in the diskor plate M, which is secured to thefront of the standard of the machine, as shown more clearly in Fig. 2.The said cam-groove consists of a series of connected short curves orarcs, approaching toward the center of the 3 machine at their junctionson the radial dotted line e c, and receding away from the center at themiddle of their length on the radial dotted lineff. Thus on rotating themandrel along with its converging or 'adial slides to the extent of oneof the said curves or undulatious-say one-eighth of a revolution in thearrangement illustrated in my drawings the slides will all be forcedinward and outward together, thereby completing the lateral perforatingof the capsule on the mandrel at each eighth of a revolution of thesame.

N is a removable ring placed over the rollers K, and screwed to the faceof the cam, in order to keep the said rollers in their grooves. Vhen itis required to change the mandrel for one of a different size or shape,the ring N is removed; also, the caps or cover-plates H of the guides G,so as to release the several slides F, when the mandrel (7, togetherwith its punch-guide d, can be unscrewed from the block E, to bereplaced by a fresh mandrel and punch-guide and corresponding set ofslides and punches.

O is a ratchetwheel fixed on the spindle B,

3 having as many teeth as there are perforated sides to the mandrel.

P P is an ordinary pawl and lever, engaging into and driving theratchet-wheel so that at each movement to the extent of one tooth of theratchet-wheel the mandrel and its converging slides will describeoneeighth of a revolution, the rollers K and slides F during suchmovement being caused to travel out ward and inward once and to repeatthe movement on passing along each of the several curves of thecam-groove in succession. The lever P may be worked either by handdirect or through a connecting-rod attached thereto at P, and receivinga longitudinal reciproserving to release or push off each capsule asfast as it is perforated. On placing a fresh capsule on the mandrel itis passed over the releaser button R, and is pushed inward along withit, and maintained in that position by the thumb or finger of theattendant during the operation of perforating until the capsule is readyto be discharged by the outward movement of the releaser R on thewithdrawal of the finger of the attendant. The throw of the releaser canbe adjusted by'the nut T.

I am aware that rotating perforated flatsided mandrels have beenproposed, in combination with separate groups of punches correspondingto the number of flat sides on the space had to be left between eachgroup of 5 punches at the junctions of the several flat sides of themandrel to permit of the free ac tion of the outer punches of thegroups. The result was that corresponding non-perforated portions of thecapsule were left at the several junction-angles of the mandrel, andthese portions could only be perforated by shifting the capsule roundthe mandrel, after the first action of the punches, to asuflicientextent to bring the unperforated part under the action of thepunches at their second stroke, whereby much time was lost and theequidistant spacing of the perforations circularly round the capsulewas, even by those means, rendered uncertain and difficult. Now, by theadoption of a mandrel having, say, eight fiat sides, as shown in thefull-sized transverse section in Fig. 4, the junction-angle between anytwo contiguous flat sides will be more obtuse, and as the groups ofpunches must work at right angles to their corresponding flat sides ofthe mandrel, facility is thereby afforded for spacing all the punches ofthe various groups I equidistantly from each other all round themandrel, there being no extra space left between the outer punches, i'5, of two adjoining groups than between the punches constituting thegroups themselves. This will be clearly understood on comparing thediagram Fig. 5 of a flat-sided mandrel and punches arranged on the oldsystem with my present improved form and arrangement of maud rel andpunches shown at Fig. 4. In Fig. 5 a wider space is necessarily leftbetween the outer punches, i i, of two adjoining groups, I, than betweenthe punches in the .groups themselves, whereas in Fi 4110 such increaseof space is necessitated.

In order to avoid as much as possible the marking or creasing of thecapsule longitudinally between each group of punches, the apices of thej unction-angles between the several flat sides may be slightly rounded.

What I claim, and desire to secure by Letters Patent 0f the UnitedStates, is-

1. A polygonal-shaped mandrel, in combination with groups of punchesworking at right angles to the flat sides thereof and spacedequidistantly around the same, as and for the purpose specified, andillustrated by Fig. 4 of the drawings.
